Abstract: L'invention concerne un procédé de production de plantes mycorhizées par des champignons symbiotiques, lequel consiste à provoquer la mycrohize sur des plantes adultes, de façon à pouvoir disposer de plantes mycorhizées qui, une fois plantées, sont immédiatement en état de produire des fructifications. Le procédé consiste à cultiver une série de plants en terrain stérile, de préférence à partir de semences, et à mycorhizer ces plants qui poussent en milieu stérile en mettant en contact leurs racines avec les racines déjà mycorhizées par le champignon choisi, prélevées dans la nature sur d'autres plantes. Les plants pilotes ainsi obtenus sont plantes dans une serre stérile ou dans une pépinière stérile. Dans cette serre ou dans cette pépinière, on plante ensuite les plantes adultes destinées à être mycorhizées et qui ont été auparavant soumises à un procédé d'élimination des racines secondaires et de stérilisation des racines restantes. Les plants pilotes provoquent la mycorhize par le champignon choisi des plantes adultes qui sont ainsi en état de produire immédiatement des fructifications.

Abstract: Procédé et dispositif pour le freinage d'une roue, notamment d'un aéronef roulant sur le sol, au moyen d'un frein alimenté en fluide sous pression à partir d'une source à pression stable et par l'intermédiaire d'un organe de commande actionné volontairement. L'actionnement de l'organe de commande est transformé en une première suite temporelle d'impulsions électriques à fréquence constante, telles que la durée de chacune de celles-ci est une fonction croissante de l'amplitude instantanée de l'actionnement. Ensuite, la première suite d'impulsions est transformée en une seconde suite temporelle correspondante d'impulsions de pression du fluide, telle qu'à chaque impulsion électrique soit associée une impulsion de pression représentative de celle-ci. Finalement, on intègre les impulsions de pression de la seconde suite, afin d'obtenir une pression moyenne que l'on applique au frein.

Abstract: ABSTRACT Disclosed is an apparatus for producing artificial reverberations by means of a uni-dimensional wave-guide, the said uni-dimensional wave-guide being obtained with digital-technology circuits and comprising at least two line-sections of different lengths, each line-section consisting of two digital delay-arrangements running parallel with each other, one for each direction of propagation.  Furthermore, at least one three-gate adapter, of the wave-digital-filter type, is arranged between two line-sections adjacent each other, two gates of the said three-gate adapter each being connected to one of the two ends, facing each other, of the said two line-sections, and the relevant gate of one three-gate adapter being closed off by a frequency-dependent absorber obtained by digital-technology.  Digital implementation of a uni-dimensional wave guide, fitted with discontinuities and absorbers, now makes it possible to reverberate a signal diffusely and with programmable reverberation-time frequency-response, without having to made allowances for a reduction in signal-to-noise ratio as a result of limit-cycles.

Abstract: ABSTRACT OF THE INVENTION The input data samples for a fringe field responsive electro-optic line printer are differentially encoded, thereby reducing the number of electrodes such a printer requires to achieve a given resolution by a factor of just less than two. The sample-to-sample voltage drops of the differentially encoded data correspond to the magnitudes of the input samples and, therefore, the fringe fields produced when the encoded samples are applied to the electrodes of such a line printer cause the incident light beam to be spatially modulated in accordance with the input samples.

Abstract: TITLE            REBUILT COKE OVEN HEATING CHAMBER AND      METHOD OF MAKING THE SAME     ABSTRACT OF THE DISCLOSURE     A spalled and deteriorated portion of a refrac-tory brick heating wall of a coke oven heating chamber is dismantled.  The deteriorated brick  is  removed with the undamaged brick remaining in place.  Individual thermally destructable forms forming the gas flow passageways are vertically erected surrounding ports in the floor through which preheated gas and preheated air are separately supplied  into the heating chamber.   A second set of destructable forms having passageways forming the heating flues for receiving the products of combustion are posi-tioned  between  the  forms  for  the  gas  flow passage-ways.   Horizontal forms, also forming gas flow passage-ways, connect adjacent vertical forms for the flow of air and gas from the ports  into the heating flues where combustion of the air and gas takes place.   When the thermally destructable forms are  in place,  a refractory material is sprayed onto the outer surfaces of the forms.          The refractory material  is built up on the forms to replace the removed bricks to reconstruct the portion of the heating chamber removed.   The rebuilt portion is united by the refractory spraying with the brickwork of the original heating chamber that remains to form the rebuilt portion of the heating chamber integral with the original brick portion of the heating chamber.  The heat generated by the products of combustion of the air and gas disintegrate the destructable forms leaving the formed and solidified refractory replacement portion of the coke oven heating chamber.

Abstract: Tobacco Product Abstract A tobacco product such as a cigarette having a tobacco column within a combustible wrap and a filter plug located at one end of the tobacco column to filter constituents of the mainstream smoke.  The filter plug is disposed within a layer of plug wrap which preferably is nonporous and an outer tipping wrap surrounds the plug wrap.  A plurality of grooves or depressions formed along the filter plug provide for a secondary flow-of air to the mouth of the smoker.  An access opening communicating secondary air to each groove is defined by a plurality of perforations located in one or more rows or bands around the outer tipping paper.  Depressions located along axes parallel to the axis of the filter member or disposed in a helical pattern may be used.  In a second form of the invention, the access opening communi-cating secondary air to each groove is defined by an annular opening between individual portions of the outer tipping paper.  In both forms of the invention the access opening is spaced away from the junction between the tobacco column and filter plug.  The tobacco product has draw re-sistance lower than that typically found in conventional ventilated high filtration cigarettes.

Abstract: ABSTRACT OF THE DISCLOSURE The rope sling device is formed by a base plate, a stationary friction cylinder, an eccentrically pivoting auxiliary friction device, and another braking surface.  If the person to be lowered is suspended on the base plate, the rope runs between the auxiliary friction device and the other braking surface, it is also diverted at the auxiliary friction device by ca. 180°, it runs around the stationary friction cylinder with 2-1/2 windings, and leaves the rope sling device upward.  In lowering, the person to be lowered is slowed down because of the fact that a frictional force occurs at the stationary friction cylinder.  A frictional force is also formed when the rope runs over the auxiliary fric-tion device.  If the lever 64 is left alone, then the auxiliary friction device connected to it is pivoted by the frictional force of the rope sliding over it so that is presses the rope against the other braking surface, until the rope comes to a stop because of the automatic clamping.  The person to be lowered, however, can turn the lever, which is connected to the auxiliary friction device through the gear so that it unlocks or loosens the automatic clamping and no braking occurs on the brake surface.     The stop is then released and the rope sling device moves down-ward on the rope.
